Quantum Dot Artificial Atom systems electrons are confined in all three spatial directions. They are often called artificial atoms because their physics is analogous to that of real atoms. However, quantum dots have the enormous advantage that their behaviour is tunable. For example, unlike in a real atom, it is possible to control the number of electrons in a quantum dot from zero up to a few tens or even hundreds.

Quantum Dot Artificial Atom are often referred to as artificial atoms since their electronic properties, for example the ionization energy and discrete excitation spectrum, resemble those of real atoms. We have recently fabricated a circular disk-shaped quantum dot, and observed atomic-like properties by measuring Coulomb oscillations.

To understand Quantum Dot Artificial Atom it is helpful to know how to make them. One way to confine electrons in a small region is by employing material boundaries—by surrounding a metal particle with insulator, for example. Alternatively, one can use electric fields to confine electrons to a small region within a semiconductor. Either method requires fabricating very small structures. This is accomplished by the techniques of electron and x-ray lithography.

Essentially Quantum Dot Artificial Atom are small boxes about 100 nm on a side contained in a semiconductor, and holding a number of electrons that may be varied at will. As in real atoms, electrons are attracted to a central location, in a natural atom this central location is a positively charged nucleus, in an artificial atom, electrons are typically trapped in a bowl like parabolic potentional bowl one can consider the artificial atom as a tiny laboratory in which quantum mechanics ant the effect of electron – electron interactions can be studied.

Quantum Dot Artificial Atom can be formed in many different ways and from many different materials. Different types of dots are useful or interesting for different reasons but here the focus is on semiconductor quantum dots. Perhaps the simplest semiconductor dots are spherical nanocrystals that are often formed chemically.
